Installation considerations

Clearances and requirements

The custom insert unit is designed for installation inside a
custom-built hood assembly. It is for ducting to the
outside. It cannot be used in conjunction with a
recirculation unit.

Hood installation height above a cooktop, rangetop or
range can vary. To obtain the necessary installation height
above a cooktop, rangetop or range, consult the

appliance's installation manual.

Hood width

The hood width should be no less than the width of the
cooking surface. For proper performance, the housing
must cover the entire cooking surface.

For proper performance, the hood must be centered
horizontally above the cooking surface. Where space is
not restricted, a wider hood can be used to increase
capture area.

Distance from cooking surface

The installation height ranges from a minimum height of
30'' (762 mm) to a suggested maximum height of 40''
(1,016 mm); however, it is necessary to follow the cooking
appliance manufacturer’s installation instructions for
proper hood height.

Unit weight

This vent hood is heavy. Adequate structure and support
must be provided in all types of installations. When
calculating the load for the housing support system, be

sure to consider the weight of the ventilation unit.

* Follow cooking appliance manufacturer’s

NOTICE: The hood could incur some damage from heat if

Blower motors

Integral, In-line and Remote blowers are available through
your authorized Thermador
information, visit the Find a Dealer section of our website
at www.thermador.com.

The blower performance options will vary in cubic feet per
minute (CFM) and is dictated by the cooking surface, the
volume of air that needs to be moved and the length of
the duct run. Refer to the “Blower Motor Installation”
section for detailed blower motor information.

dealer. For local dealer

Support structure

Due to the weight of the hood, make sure the hood is
attached to all available wall studs.

Framing must be fastened together and to ceiling joists to
provide enough structural strength to support the weight
of the hood and internal blower, if applicable.

Wall framing should be, at minimum, made of 2"x 4"
lumber. Proper structural support is required to
accommodate the weight of the hood.

NOTE: The 25 ft. Remote and In-line Blower Extension
Cable accessory (EXTNCB25W) will only work for
distances up to 25 ft. The accessory cable must be
purchased separately. DO NOT use more than one Blower
Extension Cable per installation.

Electrical data

Data, including the model and serial number, is located on
the product data rating label inside the appliance, visible
after removal of the filter frame (see “Product Data Rating
Label”).

Electrical requirements

The unit requires a 120V AC, 60Hz. 15A branch circuit. The
VTR1330 blower in conjunction with a PHxxGWS requires
a 20 amp circuit breaker. The hood should only be
connected to a dedicated circuit (with ground) that has
been installed according to relevant regulations.

When connected to a GFCI-protected supply, Thermador

that are protected from outside weather conditions and
not subject to saturation with water and other liquids, but
can be subject to moderate degrees of moisture (such as
an outdoor covered patio or lanai area). Refer to local
codes, NEC/CEC, and or the Authority Having Jurisdiction
(AHJ) for additional information.

Check your local building codes for proper method of
installation. In the U.S., this unit should be installed in
accordance with applicable local codes or, in the absence
of local codes, with the National Electrical Code, NFPA 70
or the Canadian Electric Code, CSA C22.1-02.

9 WARNING

hoods are suitable for use in damp locations

The appliance must be grounded.

Page. 9

Ductwork preparation

Discharge direction

The exhaust air is discharged upwards through a duct or
directly through the outside wall into the open.

Ducting recommendations

Proper performance is dependent upon proper ducting.
Local building codes may require the use of make-up air
systems when using ducted ventilation systems greater
than specified cubic feet per minute (CFM) of air
movement. The specified CFM varies from locale to
locale. It is the responsibility of the owner and the installer
to determine if additional requirements and/or standards
apply to specific installations.

DO NOT USE FLEXIBLE DUCT; it creates back pressure/
air turbulence and reduces performance. Always install a
metal vent cover where the ductwork exits the house.
Hood must be vented to the outside of building only.

MAKE-UP AIR: Local building codes may require the use
of make-up air systems when using ducted ventilation
systems greater than specified CFM of air movement. The
specified CFM varies from locale to locale. It is the
responsibility of the owner and the installer to determine if
additional requirements and/or standards apply to specific
installations.

To reduce risk of fire and to properly exhaust air, be sure
to duct air outside. Do not vent exhaust air in spaces with
walls or ceilings or into attics, crawl spaces or garages.

The unit cannot be used in conjunction with a recirculation
unit.

Thermador recommends not exceeding 50 ft
(15.24 m) equivalent of duct.

Keep duct runs as short and straight as possible. Elbows
and transitions fittings reduce air flow efficiency. Back to
back elbows and “S” turns give very poor delivery and are
not recommended.

A short, straight length of duct at the inlet of a remote
blower gives the best delivery.

COLD WEATHER installations should have an additional
backdraft damper installed to minimize backward cold air
flow and a nonmetallic thermal break to minimize
conduction of outside temperatures as part of the
ductwork. The damper should be on the cold air side of
the thermal break. The break should be as close as
possible to where the ducting enters the heated portion
of the house.

Hoods are supplied with a 10" (254 mm) transition. A
locally supplied transition is required for other sizes.

Use the “Equivalent Duct Lengths for Commonly Used
Transitions” table to compute permissible lengths for duct
runs to outdoors.

Hood transition

It is recommended to use only Thermador blowers with
Thermador ventilation hoods. See the
Guide for recommended blowers. Contact Customer
Service for additional options (see the back page for
contact information).

IMPORTANT: Cutting off a connector to the appliance,
blower, or to the extension cable kit will void the warranty.

Blower selection will vary based on the volume of air that
needs to be moved and the length and location of the
duct run. For long duct runs with multiple turns and
bends, consider using a more powerful blower. For the
most efficient air flow exhaust, use a straight run or as few
elbows as possible.

Ventilation Planning

Integral blowers

These blowers are integrated into the hood at the time of
installation.

Remote blowers

Depending on preference and ducting situation, these
blowers can be mounted on the roof or exterior wall of the
home. An exterior installation may be more appealing to
reduce noise in the kitchen.

In-line blowers

To minimize noise in the kitchen, these blowers are
mounted along the duct line anywhere between the
kitchen and the exterior wall. If there is easy access to duct
line (in an attic, for example), this may be an appealing
option.

25 ft. remote and in-line blower extension
cable

Discharge direction

The exhaust air is discharged upwards through a duct or
directly through the outside wall into the open.

The hood can be mounted on the wall only with a vertical
discharge.

Assembly of the transition

Hoods are supplied with a 10" (254 mm) round transition.
A locally supplied transition is required for other sizes.

1. A minimum height clearance of 7-7/16'' (189 mm) is
needed above the hood for transition mounting.

2. Align mounting holes at base of transition over the
mounting holes of the 1/2'' (13 mm) flange located at
the top of the hood.

3. Fasten transition to hood using four (4) 1/4'' (6 mm)
sheet metal screws included with hood.

Note: Screws must not hinder damper operation.

4. Seal connection between transition and hood with
aluminum tape. DO NOT use duct tape. Ensure that

the connection is completely sealed.

The 25 ft. Remote and In-line Blower Extension Cable
(EXTNCB25W) is available to connect the hood to the In­line and Remote Blowers for distances up to 25 ft.
Accessory cable must be purchased separately. DO NOT
use more than one Blower Connector Cable per
installation.

5. Remove tape holding damper closed.

9 CAUTION

To reduce the risk of fire and electric shock, install this
range hood only with the blowers listed in the
Ventilation Planning Guide.

NOTE: Cutting the plug of the blower will void the
warranty or eligibility for return or exchange.

All blower models are sold separately. Use only
Thermador blowers with these ventilation hoods. See the
Ventilation Planning Guide for recommended blowers.
Contact Customer Service for additional options.

Integral blower models are integrated into the hood at the
time of installation. Integral blowers should be installed
after the hood is mounted to the wall.

For complete installation instructions see the instructions
supplied with the blower unit.

1. The blower is attached to the hood using weld studs
on the mounting plate. Guide the motor mounting
plate over the studs.

2. Attach four (4) nuts (included with hood) to the weld
studs. Tighten nuts with a 11/32'' nut driver to secure

the blower to the hood.

All hood models are rated for 120V AC installed with a
blower listed in the table above, using a 15 amp
dedicated circuit breaker. The VTR1330 blower in
conjunction with a PHxxGWS requires a 20 amp circuit
breaker.

Blower selection will vary based on the volume of air that
needs moved and the length and location of the duct run.
For long duct runs with multiple turns and bends, consider
using a more powerful blower. For the most efficient air
flow exhaust, use a straight run or as few elbows as
possible (refer to “Ductwork Preparation”).
